Here are some
links to Tips, Tricks and Upgrades for the 450 Helis:
EXI/Exceed 450 :
1) Chinese Weight Mod
for better Tail response
2) Use 2mm screws and nuts to fasten your servos. Stock plastic nuts
with the kits will come loose over time.
3) Download the Align
450 SEV2 manual for reference (espcially helpful in head
4) Set your head up
for symetry and level your swashplate
5) Make your skids and boom more visible: Apply
bright yellow or orange vinyl film to the boom and/or skids.
Vinyl film is available at some office supply stores or auto parts
stores (pin striping).
6) If you are a beginner or novice, Use inexpensive Fiberglass
325 or 335mm blades
7) If you have trouble w/ your tail twisting on you then rough up the boom and the inside of
You can do this on either the plastic or metal versions. Use
Xacto blade to cut in 4-5 groves on each side of the tailbox and boom.
cuts are made Parallel (Left/right) to the boom as showin the
pictures. You can also put scotch tape on the boom and try to slide the
boom in w/o crinkling up the tape. Here is a mod on
a plastic tail boom (the Blueray PE helicopters already have a screw on
the fin side in the middle for this.
If you are having trouble with the belt tention
staying tight, Use an Xacto blade to cut 4-5 groves on each side of the
front of the boom and inside the boom block. Make the cuts on the sides
only and where the boom block meets the boom. Cut the boom as well as
the boom block Perpendicular (UP/DOWN) to the boom.
Another method is a
strip of scotch tape wrapped from 7 oclock around the top to 4 oclock
(not all the way around boom). Before inserting, you much loosen the
boom block up enough to fit the boom with tape into it w/o wrinkling
the tape. Pull boom then tighten.
9) Have one of those Inexpensive G401B gyros? Try this MOD
10) Keep your skids from rotating by using a screw on the skid
EXI 450 specific :
1) Switch to Carbon
Fiber Frame from (if yours is metal and bending in a crash)
to Nuttcaze's tutorial on the EXI Squadron 450 build.
Xheli RTF kit specific :
1) My suggested upgrade
2) Use the EXI
450 spare parts list to save $$ over Align parts
If you are crashing alot, once you crash the first time then upgrade to
metal gear'd servos. (NOTE, Xheli Bluerays are now comming with MOSTLY
metal gear'd servos. And the one lower gear is plastic. Replacement
gearsets for the original Blueray servos are available at
hobbypartz.com. Replacing the gearsets is not that hard.
